When having a long chat in a session, at some point, there is this "memory cutoff" red line that appears when one scrolls back. I expect that's because that's where the AI had to "forget" things. It would be neat to have a button, say in the bottom right hand corner of the chat, that appears when such a memory cutoff happens, so that the user could jump back from time to time to get an idea of what the AI "forgot" during this chat.

Not sure I'm explaining it very well. I'm always concerned, in a chat session, when the AI will start forgetting stuff and just hallucinating things rather than say "I forgot".
